Yes I am working my way ahead. And I think it works the way it is intended, when I set it up the way you explain.
I am, though, having difficulties finding a proper position for the fbmodule. Partly because it ought to bepositioned around the js loginmodule to make sense to the user, and patly because it stays (and expands) when logged in, which is a challenge to the rest of the layout. It therefore would be better if it just integrated into the excisting js loginmodule.
Second, it seams to me that it does not integrate that much into js as I will loose my stream in the profile, mike likes etc. These are applications that is integrated into the js fb-connect.
So, bottum line is that, what I get out of the fbconnet is more or less the fb-invite. And the "cost" is loosing all the other integration and challenging my layout.
Am I wrong? I hope so...
